Dental infections originating in the teeth are routinely managed systemically with a course of oral antibiotics, while severe forms are managed with intravenous antibiotics. Dental infections can also be managed by removing the offending cause of the infection followed by placement of an intra-canal medication which acts as a local antimicrobial. Intra-canal medicaments are being used in clinical practice following root canal treatment. The investigators hypothesize that the effect of intra-canal antimicrobials in the management of dental infections will be the better than oral antibiotics in terms of clinical , microbial and oral- health quality of life parameters. This will be a three-arm, parallel, comparative, randomized study with the aim of assessing the efficacy of intra-canal medication and oral antibiotics in reducing the infection and treatment of odontogenic infections, based on signs and symptoms and microbial count. The study will be performed in child participants between the age group of 3 to 11 years presenting with acute odontogenic infections. Participants will be randomized by block randomization. The treatment duration of the study will be at least 5 days or maximum 7 days depending upon the response. Participants will be assessed on Day 3 and Day 5/7. Concurrently, the oral health-related quality of life (OHRQoL) following these clinical interventions in children will be recorded and again on Day 14. Quantitative assessment of microorganisms seen in the root canals and the changes seen in the microbial flora through the treatment will help us to determine the best antimicrobial agent to be used in the management of odontogenic infections.
This study will comprise of a three-arm, parallel, comparative, randomized treatment of children aged 3 to 11 years presenting with acute odontogenic infection. The three arms of the study includes 1) Odontopaste® as a one time intra-canal placement, 2) Calcium hydroxide (gold standard) as a one time intra-canal placement and 3) a course of amoxicillin three times daily for 5 days administered orally with meal. Patients will not receive additional medical therapy such as analgesics or anti-inflammatory drugs. The participants will be selected for the treatment based on a block randomization in groups of three. On Day 1 after confirming the eligibility based on clinical examination and radiographic finding, informed consent will be obtained. At baseline (Day 1), clinical parameters including pain,swelling, regional lymphadenitis, percussion of the tooth, trismus, fistula and pus discharge will be recorded. Participant will undergo an intervention whereby the tooth will be opened from the clinical crown followed by microbiological sampling, drainage and irrigation of the tooth, intra-canal medicament placed in the canals according to randomization and the cavity sealed with a Glass ionomer cement. Participants in the oral antibiotic group will have no intra-canal medicament placed and instead a sterile cotton pellet placed. Simultaneously, the Malay-ECOHIS will be given to the parent/guardian of the participant. The microbiological sampling will be stored in an appropriate transport medium and sent to the central laboratory for quantitative assessment via quantitative polymerase chain reaction (qPCR) using SYBR® Green. Participants will be assessed on Day 3 for clinical parameters and the integrity of restoration. The next and final assessment will be done at Day 5/7, where clinical parameters will be recorded along with microbiological sampling as in Day 1. The Malay-ECOHIS survey will be repeated. The primary objective of the study is to assess the resolution of the infection based on 1) clinical parameters, 2) microbiological sampling and 3) oral health quality of life. The treatment will be carried out by five operators who are calibrated and the individual sub components such as recording clinical parameters, microbiological sampling and assessing the OHRQoL questionnaire will be carried out by the same operator respectively.

Mean Change From Baseline in Wong Baker Faces Pain Rating Scale of Pain Score at Day 3, Day 5 or 7
Wong Baker Faces Pain Rating Scale (WBFPRS) is used to measure the amount of pain that a participant experiences. This scale has numerical ratings from 0 to 10. Zero indicates no pain and 10 indicates worst possible pain. Change in Pain is documented as WBFPRS score at Baseline and subsequent reviews.
Time frame: Baseline, Days 3, 5 or 7
Mean Change From Baseline in Visual Rating Scale of Swelling Score at Days 3, 5 or 7
Visual Rating Scale (VRS) is used to measure the degree of swelling that the participant experiences. This scale has numerical ratings from 0 to 5. Zero indicates no swelling pain and 5 indicates worse swelling imaginable. Change in Swelling is documented as VRS score at Baseline and subsequent reviews.
Time frame: Baseline, Days 3, 5 or 7
Mean Change From Baseline in Regional Lymphadenitis Score at Days 3, 5 or 7
Examination of lymph nodes is performed and recorded as 0,1 and 2. Zero indicates no inflammation of lymph nodes; 1 is described as inflammation of regional lymph nodes, palpatory examination painless, and a score of 2 indicates inflammation of regional lymph nodes, palpatory examination painful.
Time frame: Baseline, Days 3, 5 or 7
Mean Change From Baseline in Temperature Score at Days 3, 5 or 7
Temperature is recorded as baseline and on review visits as 0,1 and 2. Zero indicates afebrile (up to 36.9 °C),1 as subfebrile (37-37.9 °C) and 2 as febrile (38 °C and more)
Time frame: Baseline, Days 3, 5 or 7
Mean Change From Baseline in Trismus Score at Days 3, 5 or 7
Distance measurement between incisal ridge of upper and lower jaw in case a patient had the teeth and in case the teeth were missing the measurement was based on the distance between alveolar ridges of the frontal region. The measured results were evaluated according to the established scale: 0 - there is no trismus (21 mm and more),1 - slightly pronounce trismus (11- 20 mm) and score 2 as very pronounced trismus (0 -10 mm).
